All of these “redeposited” limestones could be considered clastic sedimentary rocks, as well as organic sedimentary rocks.

Sedimentary rocks contain information about what was occurring on earth’s surface at the place and time the sediments were deposited. In some cases sedimentary rocks contain fossils, which provide information about what was living at a certain place and time on earth. There are two main groups of sedimentary rocks: chemical and clastic.Almost all of carbonate reservoir type accumulated as a shallow marine sedimentary, except on a pelagic chalk and deep marine re-sediment reservoir carbonate in Mexico seas. Carbonate reservoir rocks can be found as a clastic limestone, carbonate framework (reef), and dolomite. Reef Reservoir

Clastic Sedimentary Rocks: Clastic rocks are formed from the accumulation and lithification of fragments of other rocks and minerals, known as clasts. ...

Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone.Sedimentary rocks are classified into three groups: Clastic, Biologic, and Chemical. Key Terms . Cementation: The process by which clastic sediments become lithified or consolidated into hard, compact rocks, usually through deposition or precipitation of minerals in the spaces among the individual grains of the sediment.1) Clastic -- discrete fragments cemented and compacted together; all detrital sedimentary rocks have clastic texture. 2) Nonclastic or crystalline -- minerals form a pattern of interlocking crystals. Clastic. Rocks with a clastic texture consist of discrete fragments and particles that are cemented and compacted together.Clastic sedimentary rocks are dominated by components that have been transported as solid clasts (clay, silt, sand, etc.). In contrast, chemical and biochemical sedimentary rocks are dominated by components that have been transported as ions in solution (e.g., Na +, Ca 2+, HCO 3 –, etc.). There is some overlap between the two because almost ...Detrital or clastic rocks. sediment transported as solid particles (ex.: sandstone) Chemical rocks. sediment that was once in solution (ex.: NaCl, rock salt) Biochemical rocks. formed by organisms (limestone, chalk) Clastic rocks-Discrete fragments and particles-All detrital rocks have a clastic texture.

The sediment is dominated by debris derived from coccolithophorid algae that comprise a spherical calcareous test (coccosphere) up to several tens of microns in ...Chalk is typically almost pure calcite, CaCO3, with just 2% to 4% of other minerals. These are usually quartz and clay minerals, though collophane (cryptocrystalline apatite, a phosphate mineral) is also sometimes present, as nodules or as small pellets interpreted as fecal pellets. If non-clastic rocks are fine-grained enough, they too can be called aphanitic. Clastic sedimentary rocks are subdivided on the basis of grain size. Secondary characteristics used to further distinguish clastic rocks are sorting, grain shape, and grain composition. Grain size: Clastic sediments are distinguished on the basis of average grain size.
